Comparative Study of XPM- and SRS-Induced Crosstalk in Optical Fiber Transmission Systems Ⅱ--Cascaded Transmission System
Intensity/phase transfer matrices are derived to characterize both cross phase modulation (XPM) and Stimulated Raman Scattering (SRS) in cascaded IM DD optical fiber transmission systems. Based on the calculation of intensity noise spectrum, comparative study of XPM and SRS induced crosstalk is performed analytically and numerically. Analysis reveals that SRS and XPM leads mainly to low frequency and high-frequency noise, respectively; crosstalk from adjacent channels is mainly attributed to XPM while that from channels afar mainly attributed to SRS; in cascaded transmission systems, crosstalk noise power from SRS may even exceed that from XPM. Finally, some suggestions are proposed for the design and analysis of DWDM systems.
